<h3>Create Your Own Databases</h3>

<p>The simplest way to create a database is using DATABASE, see
<a href="DB_Add_data.htm">Adding Data with DATABASE.</a></p>

<p>Because databases are plain text files, you can also use
a text editor to create databases. A database consists of two files:</p>
<ul>
<li>A <b>logK-file</b> includes stoichiometry and <nobr>log<i>K</i></nobr> values
for reactions.</li>

<li>An <b>elements-file</b> has information on which components should be
listed under a given chemical element.  For example, one might add a new ligand:
<i>glycinate</i>, which should be listed under the element <i>carbon.</i> The program has no
way of knowing this unless you enter the information in the element-file.</li>

</ul>

<p><b>File Names:</b> These two files (the logK-file and the element-file) are plain text files
and must have the same name but different extensions: <tt>ELM</tt> for the element-file,
and either of: <nobr><tt>TXT</tt>,</nobr> <nobr><tt>SKV</tt>,</nobr> or <tt>CSV</tt>
for the logK-file. For example, a database could consists of the two files:
<nobr><tt>glycine.elm</tt>&nbsp;</nobr>  and
<nobr><tt>glycine.txt</tt>.</nobr></p>

<p>
<b>Format of the database files:</b>
<ul>

<li>
<a href="DB_logK_files.htm"><b>logK-files</b></a></li>

<li>
<a href="DB_Element_files.htm"><b>element files</b></a></li>

</ul></p>
